Effects of Salinity, molybdenum and mycorrhizal fungi (Glomus versiform) on the oxidative enzymes activity and some physiological characteristics in corn
To evaluate the effects of salinity, molybdenum and mycorrhizal fungi (Glomus versiform) on corn, a plot experiment was conducted as factorial in a completely randomized design with three replications at the University of Shahrood in 2014.The experimental treatments were three levels of molybdenum 0 ,10 and 20 mg Mo/kg soil, three levels of salinity included: 0, 4 and 8 dS/m and two levels of inoculation and without inoculation with the mycorrhizal fungi (Glomus versiform). The results showed that, the highest activity of catalase was obtained at the 4 ds/m of salinity treatment and 20 mg Mo/kg. Therefore the highest activity of guaiacol peroxidase was in the 8 ds/m salinity treatment and at the presence of mycorrhizal fungi. The interaction between the three treatments of salinity, molybdenum and mycorrhizal fungi had significant effect on the amount of chlorophyll "b", sodium, potassium and molybdenum content in leaves. The highest content of molybdenum in leaves was obtained at the presence of the fungus, the highest level of molybdenum and the 0 salinity treatment. In this experiment, the results showed that, the highest amount of chlorophyll "b" was obtained at the 20 mg Mo/kg , 8 ds/m of salinity and at the the presence of mycorrhizal fungi. As well as the inoculation of mycorrhizal fungi and use of 20 mg Mo/kg caused of increasing potassium and decreasing of sodium absorption corn
